Thank you so much!

Looks like its Global Children's Center. Bottom link under Announcements on the school website.

Thanks for that information. He will most likely attend Brookhaven. Do you know anything about programs there?

Almost every public ES in Montgomery County, including those in the Aspen Hill area, has B/A care at the school. They are run by private companies, but you should be able to get info from the school website or by calling the office. If you tell us which ES we can tell you which provider. Some are awesome, most are at least OK.
As to when to start looking, you can get the info now. Most will open registration for the 2018/19 school year next spring.

Next year, when my LO goes to kindergarten, we will need before and after care for him. We live in Aspen Hill. Any recommendations? When should I start looking?
